JavaScript Objects and Prototypes

Create Objects

  • Using function
    • Create Objects without duplication code: use functions
  • Using constructors
    • To indicate a function is a constructor: 
      • append new keyword in front of the function name when executing it
Call

  • Property of function object
  • foo.call() = foo()
  • Call can bind different objects and can execute functions
__proto__

  • Copy of prototype object

  • If some property is not in the object itself, it then looks it in the prototype. If it finds it returns the value of that property
  • All the new object instances of function point to same prototype object
  • prototype.constructor: property that points to function

Core Java Concepts

Java Applications  There are mainly four types of Java applications. Standalone Web  Enterprise  Mobile Java Features  There are several features in Java, but in here listed some important ones Platform independent Object oriented Multi threaded Distributed Robust (automatic garbage collection, exception handling, type checking) Java Security  Java has 3 built-in security components; Classloader: Separate class files packages from imported packages. BytecodeVerifier: check the illegal access to objects Security Manager: check what resources can access the object. C++ vs Java Methods Static - No need to create an object to invoke the static method. Constructor - use to initialize objects Constructor name must same as the class name Constructor has no return type There are two types of constructors Default - no parameter Parameterized If there is no constructor defined in the class, compiler aut...
